Thermocouple Channel Properties (AI)

Last Modified: March 27, 2020

Configure analog input (AI) channel properties to measure temperature using a thermocouple.

Thermocouples require cold-junction compensation (CJC) for temperature references. For more information on measuring temperature, refer to the NI-DAQmx Manual.

Property/Section Description
Minimum Value The minimum value you expect to measure before VeriStand performs any scaling or calibration.
Maximum Value The maximum value you expect to measure before VeriStand performs any scaling or calibration.
Thermocouple Type Specifies the type of thermocouples connected to the channel. Thermocouple types differ in composition and measurement range.
  • B—B-type thermocouple.
  • E—E-type thermocouple.
  • J—J-type thermocouple.
  • K—K-type thermocouple.
  • N—N-type thermocouple.
  • R—R-type thermocouple.
  • S—S-type thermocouple.
  • T—T-type thermocouple.
CJC Value Specifies the temperature of the cold-junction if you set the CJC Source property to Constant Value.
CJC Source Specifies the source of cold-junction compensation:
  • Constant Value—Use the CJC Value property to specify the cold-junction temperature.
  • Internal—Use a cold-junction compensation channel built into the terminal block.
